Type 2 diabetes glucose tolerance test questions,type 2 diabetes long term effects xanax,glycerine 30 - PDF 2016


Glucose tolerance tests help to diagnose type 2 diabetes or impaired glucose tolerance - a condition that may lead to diabetes.
I will show you an easy and safe way to assess how far down the Road to Diabetes you have already travelled.
The following test is my version of the Glucose Tolerance Test which is used by doctors to determine if you are diabetic or not. If you discover you are diabetic, you should continue to take another glucose test every hour, for another four hours, or until glucose drops below 105. According to me, there is a right way and a wrong way to eat to avoid or slow down diabetes.
Fortunately, I think that now I have finally learned to eat correctly because now I learned to test my glucose levels before and after most meals. How far down that road to diabetes we have already travelled depends on the state of our pancreas, and very few people know how well their pancreas is working. The values obtained tell a lot about your body metabolizes sugar, and the state of the pancreas. FOUR ENGINES-- You are flying high and fast, Clear weather ahead, no problems are expected. However, now that you know that you have lost one engine it makes sense that you should do everything possible to avoid losing any other engine, which would definitely not be good for your health.
Severe symptoms, including psychotic or neurotic behaviour, might occur during the traditional glucose tolerance test, but probably not with a large glass of orange juice.

I’ve read in dozens of articles across the internet that reactive hypoglycemia is one of the first signs of diabetes. In other words, if you have true reactive hypoglycemia (with symptoms appearing at 2-3 hours), the statistics say you are more likely to have a lower risk of diabetes.
In order to illustrate why it isn’t easy to give a diagnosis for any particular disease, here is a graph of two patients who have just had a Glucose Tolerance Test (GTT).
Blood glucose levels alone tell you practically nothing about your possible prediabetic status! It’s very interesting because it explains how doctors and diabetic associations have it all wrong about diabetes risk. There are economical interests as to why the Diabetic Association don’t change their criteria for diabetes diagnosis and risk. Considering this data it seems that many people with Reactive Hypoglycemia are indeed at risk for diabetes, because they have an impaired glucose tolerance. If you are just discovering your RH – please understand that it takes time for the carbo-cravings to subside.
I have not found a reason to avoid meat, but do best when I also include a sizable amount of vegetables. Using Diabetes Mellitus as an example, understand the consequences of disturbing the balance between metabolic pathways. To be able to indicate the role of insulin and glucagon in the control of carbohydrate and lipid metabolism. To be able to recognise the major symptoms of Type I and Type II diabetes and the underlying biochemical defects. To be able to use patient history and results from blood and urine tests to aid in diagnosis.
The flow diagram at the end of this exercise outlines how the energy producing pathways are connected.
During the session we will look at the changes in metabolism that occur in diabetes, the diagnosis and long term problems and use the information to evaluate two clinical cases.
Bring textbooks and notes covering biochemical and medical aspects of energy metabolism and diabetes.
This work session will help you understand and revise the lecture material on metabolism of carbohydrates and lipids. You should be getting a picture of how the pathways interact and are regulated to provide an appropriate blood glucose level, and mobilise and maintain energy reserves. Diabetes mellitus is caused by a failure to secrete, or to respond to, the hormone insulin. Diabetic neuropathy and cardiovascular disease are the major causes of death in patients over 50 years of age.
Also the polyol pathway uses NADPH - required to keep levels of reduced glutathione in cells.
Type II, and even in Type 1 the administered insulin is also likely to be above physiological levels some of the time.
You should be aware of the principle diabetic complications and how tight control of glucose and insulin levels may help to reduce these problems. Patient A: A 55 year old bus driver reported that he had cut one of his toes while trimming his nails and, several weeks later, the toe had still not healed properly and was very uncomfortable.
The handling of glucose can be studied by the glucose tolerance test, in which a standard amount of glucose is taken by the subject and the concentration of blood glucose determined at suitable intervals thereafter.
During the glucose tolerance test, two urine samples from Patient A and B and a normal urine sample were tested qualitatively for glucose and ketone bodies using Multistix reagent strips.
The shape of the glucose tolerance curve is, in part, dependent upon the efficiency of insulin secretion and information about this can be obtained by measuring plasma insulin concentrations during the glucose tolerance test by an immunoassay. Circulating levels of most hormones are very low and cannot be measured by normal chemical methods.
All immunoassays rely on highly specific antibodies which bind specifically to the hormone being measured.
Using the Risk Calculator, determine your patient’s risk score, then use the results table to calculate your patient’s diabetes risk.
Please note: Recommendations are presented for screening asymptomatic adults for type 2 diabetes using blood tests. Use your patient’s results from the risk calculator in the results table to determine the Canadian Task Force on Preventive Health Care (CTFPHC)’s screening recommendations. Have any members of your patient’s immediate family or other relatives been diagnosed with diabetes (type 1 or type 2)? The CTFPHC selected FINDRISC as the preferred risk questionnaire because it has been validated and has similar test accuracy to the Canadian Diabetes Risk Questionnaire: CANRISK. Patient important outcomes are outcomes that are of particular relevance to and valued by patients, including things like quality of life, pain control or other symptom relief, etc. The CTFPHC selected A1c as the preferred screening test, but noted that the fasting glucose measurement and the glucose tolerance test are acceptable alternatives.
The Canadian Task Force for Preventive Health Care does not provide medical advice, diagnosis or treatment.
There are two different tests your doctor can use to measure your blood glucose to determine if you have pre-diabetes or diabetes: the fasting plasma glucose test (FPG) or the oral glucose tolerance test (OGTT). The FPG test is a blood test that determines the amount of glucose (sugar) in the blood after an overnight fast (not eating for at least 8 hours).
With the OGTT test, a person's blood glucose level is measured after fasting and then 2 hours after drinking a glucose-rich beverage.
See the chart below for the ranges of blood sugar levels and how they are used to diagnose pre-diabetes and diabetes. Both type 1 and type 2 diabetes share one central feature: elevated blood sugar (glucose) levels due to absolute or relative insufficiencies of insulin, a hormone produced by the pancreas. During and immediately after a meal, digestion breaks carbohydrates down into sugar molecules (of which glucose is one) and proteins into amino acids. Right after the meal, glucose and amino acids are absorbed directly into the bloodstream, and blood glucose levels rise sharply. The rise in blood glucose levels signals important cells in the pancreas, called beta cells, to secrete insulin, which pours into the bloodstream. When insulin levels are high, the liver stops producing glucose and stores it in other forms until the body needs it again.
About 2 - 4 hours after a meal both blood glucose and insulin are at low levels, with insulin being slightly higher. Without insulin to move glucose into cells, blood glucose levels become excessively high, a condition known as hyperglycemia. Weakness, weight loss, frequent urination, and excessive hunger and thirst are among the initial symptoms.
About 5% of pregnant women develop a form of type 2 diabetes, usually temporary, in their third trimester called gestational diabetes.
Type 1 diabetes is usually a progressive autoimmune disease, in which the beta cells that produce insulin are slowly destroyed by the body's own immune system.
Researchers have found at least 18 genetic locations, labeled IDDM1 - IDDM18, that are related to type 1 diabetes.
Most people who develop type 1 diabetes, however, do not have a family history of the disease. Some research suggests that viral infections may trigger the disease in genetically susceptible individuals.
Conditions that damage or destroy the pancreas, such as pancreatitis, pancreatic surgery, or certain industrial chemicals can cause diabetes. Type 1 diabetes can occur at any age but usually appears between infancy and the late 30s, most typically in childhood or adolescence. Children with type 1 diabetes may also be restless, apathetic, and have trouble functioning at school. The FPG test is not always reliable, so a repeat test is recommended if the initial test suggests the presence of diabetes, or if the tests are normal in people who have symptoms or risk factors for diabetes.
Patients who have the FPG and OGTT tests must not eat for at least 8 hours prior to the test. The results of a blood glucose test tell the patient and doctor how well the diabetes is controlled for only the day of the test.
Once a blood sugar molecule sticks to a hemoglobin molecule, which are found in every red blood cell, it never lets go (a process called glycation). Therefore, an elevated hemoglobin A1c level tells the doctor and the patient how well controlled the patients diabetes has been over the last 3 months or so. Measuring glycosylated hemoglobin is not generally used for making an initial diagnosis of diabetes, since a normal level does not rule out diabetes. Elevated levels of glycosylated hemoglobin are strongly associated with most if not all of the complications of diabetes. Type 1 diabetes is characterized by the presence of a variety of antibodies that attack the islet cells.
Cardiac exercise testing should be considered for adult patients with any symptoms or electrocardiogram findings, or before starting an exercise program. Protect the heart and aim for healthy lipid (cholesterol and triglyceride) levels and control of blood pressure.
Healthy eating habits, along with good control of blood glucose, are the basic goals, and several good dietary methods are available to meet them. Protein should provide 12 - 20% of daily calories, although this may vary depending on a patient’s individual health requirements.
To avoid hypoglycemia, patients should inject insulin in sites away from the muscles they use the most during exercise. Before exercising, avoid alcohol and if possible certain drugs, including beta blockers, which make it difficult to recognize symptoms of hypoglycemia.
Insulin-dependent athletes may need to decrease insulin doses or take in more carbohydrates, especially in the form of pre-exercise snacks. Patients with diabetes and high blood pressure need an individualized approach to drug treatment, based on their particular health profile. Angiotensin-converting enzyme (ACE) inhibitors reduce the production of angiotensin, a chemical that causes arteries to narrow. Calcium-channel blockers (CCBs) decrease the contractions of the heart and widen blood vessels. Nearly all patients who have diabetes and high blood pressure should take an ACE inhibitor (or ARB) as part of their regimen for treating their hypertension.
The primary safety concern with statins has involved myopathy, an uncommon condition that can cause muscle damage and, in some cases, muscle and joint pain.
Although lowering LDL cholesterol is beneficial, statins are not as effective as other medications -- such as niacin and fibrates -- in addressing HDL and triglyceride imbalances. Fibrates, such as gemfibrozil (Lopid) and fenofibrate (Tricor), are usually the second choice after statins. In virtually all cases, wound care requires debridement, which is the removal of injured tissue until only healthy tissue remains. Administering hyperbaric oxygen (oxygen given at high pressure) is showing promise in promoting healing.
Total-contact casting (TCC) uses a cast that is designed to match the exact contour of the foot and distribute weight along the entire length of the foot. Nonprescription analgesics, such as aspirin, acetaminophen, and non-steroidal anti-inflammatory drugs (NSAIDs). Topical medications, particularly capsaicin (the active ingredient in hot peppers), are applied to the skin to relieve minor local pain. Tricyclic antidepressants, such as amitriptyline (Elavil) or doxepin (Sinequan), are effective in reducing pain from neuropathy in many patients.
Duloxetine (Cymbalta), a serotonin and norepinephrine reuptake inhibitor, is approved for treatment of pain associated with diabetic peripheral neuropathy. Anti-seizure drugs used for peripheral neuropathy pain relief include gabapentin (Neurontin), pregabalin (Lyrica), carbamazepine (Tegretol), and valproate (Depakote).
Although not proven to be beneficial, patients may also try transcutaneous electrostimulation (TENS), a treatment that involves administering mild electrical pulses to painful areas. Tight control of blood sugar and blood pressure is essential for preventing the onset of kidney disease.
ACE inhibitors are the best class of blood pressure medications for delaying kidney disease and slowing disease progression in patients with type 1 diabetes.
For patients with diabetes who have microalbuminuria, the American Diabetes Association strongly recommends ACE inhibitors or ARBs.
A doctor may recommend a low-protein diet for patients whose kidney disease is progressing despite tight blood sugar and blood pressure control. Intensive blood sugar control during pregnancy can reduce the risk for health complications for both mothers and babies. To prevent birth defects that affect the heart and nervous system, women with diabetes should take a higher dose of folic acid from the time of conception up to week 12 of pregnancy.
Women with diabetes should have an eye examination during pregnancy and up to a year afterward.
Many patients experience significant weight gain from insulin administration, which may have adverse effects on blood pressure and cholesterol levels.
A diet plan that compensates for insulin administration and supplies healthy foods is extremely important.
The goal of intensive insulin therapy is to keep blood glucose levels as close to normal as possible. Table 1:Glucose Goals for Patients with Diabetes Standard insulin therapy usually consists of one or two daily insulin injections, one daily blood sugar test, and visits to the health care team every 3 months. Insulin requirements vary depending on many non-nutritional situations during the day, including exercise and sleep.
The patient must also maintain a good diet plan and should visit the health care team of doctors, nurses, and dietitians once a month. Because of the higher risk for hypoglycemia in children, doctors recommend that intensive treatment be used very cautiously in children under 13 and not at all in very young children. The catheter at the end of the insulin pump is inserted through a needle into the abdominal fat of a person with diabetes. Learning to use the pump can be complicated, although over time most patients find the devices are fairly easy to use. Insulin pumps are more expensive than insulin shots and occasionally have some complications, such as blockage in the device or skin irritation at the infusion site. Pramlintide (Symlin) is a new type of injectable drug that can help control postprandial hyperglycemia, the sudden increase in blood sugar after a meal. Both low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia) are of concern for patients who take insulin.
Different goals may be required for specific individuals, including pregnant women, very old and very young people, and those with accompanying serious medical conditions. Home monitors are about 10 - 15% less accurate than laboratory monitors, and many do not meet the standards of the American Diabetes Association.
To monitor the amount of glucose within the blood a person with diabetes should test their blood regularly.
Continuous glucose monitoring systems (CGMS) use a needle-like sensor inserted under the skin of the abdomen to monitor glucose levels every 5 minutes.
GlucoWatch is a battery-powered wristwatch-like device that measures glucose by sending tiny electric currents through the skin, a technique called reverse iontophoresis.
Hemoglobin A1c (also called HbA1c , HA1c, or A1C) is measured periodically every 2 - 3 months, or at least twice a year, to determine the average blood-sugar level over the lifespan of the red blood cell.
Some research has suggested that children (particularly thin children) are at higher risk for hypoglycemia because the injection goes into muscle tissue.
Patients who intensively control their blood sugar should monitor blood levels as often as possible, four times or more per day. In adults, it is particularly critical to monitor blood glucose levels before driving, when hypoglycemia can be very hazardous.
Patients who are at risk for hypoglycemia should always carry hard candy, juice, sugar packets, or commercially available glucose substitutes.
If the patient is helpless (but not unconscious), family or friends should administer three to five pieces of hard candy, two to three packets of sugar, half a cup (four ounces) of fruit juice, or a commercially available glucose solution. If there is inadequate response within 15 minutes, the patient should receive additional sugar by mouth and may need emergency medical treatment, possibly including an intravenous glucose solution.
Family members and friends can learn to inject glucagon, a hormone, which, in contrast to insulin, raises blood glucose. Patients with type 1 diabetes should always wear a medical alert ID bracelet or necklace that states that they have diabetes and take insulin.
Patients should inspect their feet daily and watch for changes in color or texture, odor, and firm or hardened areas, which may indicate infection and potential ulcers. When washing the feet, the water should be warm (not hot) and the feet and areas between the toes should be thoroughly dried afterward. Gently use pumice to remove corns and calluses (patients should not use medicated pads or try to shave the corns or calluses themselves). Intensive control of blood glucose and keeping glycosylated hemoglobin (HbA1c) levels below 7%. Diabetic ketoacidosis (DKA) is a life-threatening complication caused by insulin deficiency. The process is usually triggered in insulin-deficient patients by a stressful event, most often pneumonia or urinary tract infections. Severely low insulin levels cause excessive amounts of glucose in the bloodstream (hyperglycemia). These fatty acids are converted into chemicals called ketone bodies, which are toxic at high levels. Cerebral edema, or brain swelling, is a rare but very dangerous complication that occurs in 1% of ketoacidosis cases and results in coma, brain damage, or death in many cases. Other serious complications from DKA include aspiration pneumonia and adult respiratory distress syndrome. If the condition persists, coma and eventually death may occur, although over the past 20 years, death from DKA has decreased to about 2% of all cases. Life-saving treatment uses rapid replacement of fluids with a salt (saline) solution followed by low-dose insulin and potassium replacement.


Patients with type 1 diabetes are 10 times more at risk for heart disease than healthy patients. Both type 1 and 2 diabetes accelerate the progression of atherosclerosis (hardening of the arteries). In type 1 diabetes, high blood pressure (hypertension) usually develops if the kidneys become damaged. Impaired nerve function (neuropathy) associated with diabetes also causes heart abnormalities.
Atherosclerosis is a disease of the arteries in which fatty material is deposited in the vessel wall, resulting in narrowing and eventual impairment of blood flow. Diabetic nephropathy, the leading cause of end-stage renal disease (ESRD), occurs in about 20 - 40% of patients with diabetes. Diabetes is responsible for more than half of all lower limb amputations performed in the U.S.
People with diabetes who are overweight, smokers, and have a long history of diabetes tend to be at most risk. In general, foot ulcers develop from infections, such as those resulting from blood vessel injury.
Charcot foot is initially treated with strict immobilization of the foot and ankle; some centers use a cast that allows the patient to move and still protects the foot. Diabetes accounts for thousands of new cases of blindness annually and is the leading cause of new cases of blindness in adults ages 20 - 74. The early and more common type of this disorder is called nonproliferative or background retinopathy. If the capillaries become blocked and blood flow is cut off, soft, "woolly" areas may develop in the retina's nerve layer. Type 1 diabetes is associated with a slightly reduced bone density, putting patients at risk for osteoporosis and possibly fractures. Women with diabetes should also be aware that certain types of medication can affect their blood glucose levels. It is also important for women to closely monitor their blood sugar levels during pregnancy.
Major advances in islet-cell transplantation are allowing more patients to come off insulin or reduce their use of it. As soon as there are sufficient numbers of islets available for transplantation, the patient is given intravenous antibiotics and oral vitamins E, B6, and A. Once the islets have been isolated, they are injected directly in a major vein in the patient's liver.
Specific drugs, such as tacrolimus, sirolimus, or rapamycin (Rapamume), are used to suppress the immune system. This procedure is still investigational but has helped some patients with severe type 1 diabetes to become free of insulin injections. A major obstacle for the islet cell transplantation is the need for two or more donor pancreases to supply sufficient islet cells. Whole pancreas transplants and double transplants of pancreases and kidneys are proving to have a good long-term success rate for some patients with type 1 diabetes.

The information provided herein should not be used during any medical emergency or for the diagnosis or treatment of any medical condition. But now that you know that you are in trouble, you should take very good care of your two remaining engines so that you won't lose another one!
As a word of caution, the information presented cannot possibly substitute for competent medical advice. As a mathematician who teaches statistics classes at the college level, I have a pretty good idea.
The patient with the red line is overweight (with most of her fat around the hips and thighs). A Hyperglucidic Breakfast Test is the only test that will be able to tell you if you have a high sensitivity to insulin (and therefore a lower statistical risk of diabetes) or a low sensitivity to insulin (and an increased statistical risk for diabetes). It seems that a high fasting blood glucose is not even necessary to be diabetic and that it is the worse predictor of diabetes.
Reactive Hypoglycemia when connected with diabetes can be understood as resistant phase 1 insulin but excessive phase 2 insulin, whereas diabetes is resistant phase 1 insulin but unadequate phase 2 insulin. Sitting on the couch, eating that litre of Oreo Cookie ice cream (yes, I remember the carbo-munchies!) will lead you to diabetes just as fast as the non-RH crowd. I do better with rice, but even after 20 years I only consume a few tablespoonfuls with my meal.
In insulin-dependent diabetes (IDD, Type I DM), the b cells of the pancreas are destroyed by an autoimmune response, leading to failure of insulin secretion. He was considerably overweight and admitted that he had been feeling rather tired for some time. European, 19 years old) visited the Student Health Centre saying he felt 'really tired and out of sorts'.
He was advised to 'take it easy and get more sleep', but replied that he had to keep getting up in the night to 'get rid of all that beer'. Radioimmunoassay (RIA) was previously commonly used for assaying hormones but is now being replaced by immunometric type assays. The hormone-antibody interaction is measured by using a labelled hormone or antibody during the assay incubation and then separating the bound and free fractions.
These recommendations do not apply to adults already diagnosed with type 2 diabetes, those at risk for type 1 diabetes, or those with symptoms of diabetes. The literature review did not identify any studies reporting on the impact of CANRISK on patient important outcomes.
Based on evidence for screening interval, the CTFPHC suggests risk calculation at least every 3–5 years for adults 18+ years of age. A1c is commonly referred to as glycated hemoglobin, glycosylated hemoglobin, hemoglobin A1c, HbA1c, Hb1c, or HbA1c. Most web browsers can view these files, but if yours can’t, please consider installing PDF viewing software such as the free Adobe Reader.
In general, it is recommended that any blood test that is outside the normal range be repeated on a different day to confirm the diagnosis. The stress of obesity, combined with a genetically susceptible background, produces insulin resistance and impaired glucose tolerance. BackgroundThe two major forms of diabetes are type 1, previously called insulin-dependent diabetes mellitus (IDDM) or juvenile-onset diabetes, and type 2, previously called non-insulin-dependent diabetes mellitus (NIDDM) or maturity-onset diabetes.
Here, insulin and other hormones direct whether glucose will be burned for energy or stored for future use. In addition to secreting digestive enzymes, the pancreas secretes the hormones insulin and glucagon into the bloodstream.
In type 2 diabetes, the body does not respond properly to insulin, a condition known as insulin resistance. It is unknown what first starts this cascade of immune events, but evidence suggests that both a genetic predisposition and environmental factors, such as a viral infection, are involved.
The IDDM1 region contains the HLA genes that encode proteins called major histocompatibility complex.
The odds of inheriting the disease are only 10% if a first-degree relative has diabetes, and even in identical twins, one twin has only a 33% chance of having type 1 diabetes if the other has it. Over the past 40 years, a major increase in the incidence of type 1 diabetes has been reported in certain European countries, and the incidence has tripled in the U.S. Certain drugs can also cause temporary diabetes, including corticosteroids, beta blockers, and phenytoin. SymptomsThe process that destroys the insulin-producing beta cells can be long and insidious.
Widespread screening of patients to identify those at higher risk for diabetes type 1 is not recommended. The oral glucose tolerance test (OGTT) is more complex than the FPG and may overdiagnose diabetes in people who do not have it. This test examines blood levels of glycosylated hemoglobin, also known as hemoglobin A1c (HbA1c). If a patient with diabetes has elevated blood glucose on many days, more blood glucose molecules will stick to the hemoglobin molecule. These antibodies are referred to as autoantibodies because they attack the body''s own cells -- not a foreign invader. The earliest manifestation of kidney disease is microalbuminuria, in which tiny amounts (30 - 300 mg per day) of protein called albumin are found in the urine. The American Diabetes Association recommends that patients with type 1 diabetes have an annual comprehensive eye exam, with dilation, to check for signs of retina disease (retinopathy). All patients should be screened for nerve damage (neuropathy), including a comprehensive foot exam. People with type 1 diabetes must coordinate calorie intake with medication or insulin administration, exercise, and other variables to control blood glucose levels. People with diabetes, whether type 1 or 2, are at risk for a number of medical complications, including heart and kidney disease. It increases sensitivity to insulin, lowers blood pressure, improves cholesterol levels, and decreases body fat. These include weight reduction (when needed), following the Dietary Approaches to Stop Hypertension (DASH) diet, smoking cessation, limiting alcohol intake, and limiting salt intake to no more than 1,500 mg of sodium per day.
Strict control of blood pressure is critical for preventing complications of diabetes and has proven to improve survival rates.
They include atorvastatin (Lipitor), lovastatin (Mevacor and generics), pravastatin (Pravachol), simvastatin (Zocor and generics), fluvastatin (Lescol), and rosuvastatin (Crestor). Niacin has the most favorable effect on raising HDL and lowering triglycerides of all the cholesterol drugs. Taking a daily aspirin reduces the risk for blood clotting and may help protect against heart attacks. Fortunately, severe and even moderate vision loss is largely preventable with tight control of blood glucose levels.
Patients with severe diabetic retinopathy or macular edema (swelling of the retina) should see an eye specialist who is experienced in the management and treatment of diabetic retinopathy. In some cases, hospitalization and intravenous antibiotics for up to 28 days may be needed for severe foot ulcers. Debridement may be accomplished using chemical (enzymes), surgical, or mechanical (irrigation) means.
Felted foam uses a multi-layered foam pad over the bottom of the foot with an opening over the ulcer.
It is generally reserved for patients with severe, full thickness diabetic foot ulcers that have not responded to other treatments, particularly when gangrene or an abscess is present. Alternative treatments -- such as hypnosis, biofeedback, relaxation techniques, and acupuncture -- have also been reported to help some patients manage pain. Neuropathy also impacts other functions, and treatments are needed to reduce their effects.
Studies indicate that phosphodiesterase type 5 (PDE-5) drugs, such as sildenafil (Viagra), vardenafil (Levitra), and tadalafil (Cialis), are safe and effective, at least in the short term, for many patients with diabetes. Strict control of these two conditions produces a reduction in new cases of nephropathy and a delay in progression of the disease. Microalbuminuria is an accumulation of protein in the blood, which can signal the onset of kidney disease (nephropathy). Protein-restricted diets can help slow disease progression and delay the onset of end-stage renal disease (kidney failure).
Doctors recommend that pregnant women with pre-existing diabetes monitor their blood sugar levels up to 8 times daily. TreatmentInsulin is essential for strict control of blood glucose levels in type 1 diabetes. It is important to manage heart disease risk factors that might develop as a result of insulin treatment. The basal component of the treatment attempts to provide a steady amount of background insulin throughout the day. Meals require a boost (a bolus) of insulin to regulate the sudden rise in glucose levels after a meal.
Injections of insulin under the skin ensure that it is absorbed slowly by the body for a long-lasting effect. Insulin is available in several forms, including: standard, intermediate, long-acting, and rapid-acting. Insulin lispro (Humalog) and insulin aspart (Novo Rapid, Novolog) lower blood sugar very quickly, usually within 5 minutes after injection.
Regular insulin begins to act 30 minutes after injection, reaches its peak at 2 - 4 hours, and lasts about 6 hours. Regimens generally include combinations of short and longer-acting insulins to help match the natural cycle. An insulin pump can improve blood glucose control and quality of life with fewer hypoglycemic episodes than multiple injections.
Some are worn externally and are programmed to deliver insulin through a catheter in the skin or the abdomen. Studies indicate that even very young children (ages 2 - 7 years) can successfully use insulin pumps and that the pumps may help improve blood sugar control. Dosage instructions are entered into the pump's small computer, and the appropriate amount of insulin is then injected into the body in a calculated, controlled manner.
In spite of early reports of a higher risk for ketoacidosis with pumps, more recent studies have found no higher risk.
Pramlintide is injected before meals and can help lower blood sugar levels in the 3 hours after meals.
Side effects may include nausea, vomiting, abdominal pain, headache, fatigue, and dizziness. Most doctors believe, however, that they are accurate enough to indicate when blood sugar is too low. While fingerprick self-testing provides information on blood glucose for that day, the HbA1c test shows how well blood sugar has been controlled over the period of several months.
These tests should always be performed during illness or stressful situations, when diabetes is likely to go out of control. Pinching the skin so that only fat (and not muscle) tissue is gathered or using shorter needles may help.
For example, taking a fast-acting insulin (insulin lispro) before the evening meal may be particularly helpful in preventing hypoglycemia at bedtime or during the night. This approach can help prevent complications due to vascular (blood vessel) abnormalities and nerve damage (neuropathy) that can cause major damage to organs, including the eyes, kidneys, and heart.
Blood glucose control helps the heart, but it is also very important that people with diabetes control blood pressure, cholesterol levels, and other factors associated with heart disease. Other triggers include alcohol abuse, physical injury, pulmonary embolism, heart attacks, or other illnesses.
Among young patients, the youngest children and boys of any age are at higher risk for hypoglycemia. Hypoglycemia unawareness is a condition in which people become accustomed to hypoglycemic symptoms.
Mild symptoms usually occur at moderately low and easily correctable levels of blood glucose. Heart attacks account for 60% of deaths in patients with diabetes, while strokes account for 25% of such deaths.
Severely restricted blood flow in the arteries to the heart muscle leads to symptoms such as chest pain. With this condition, the tiny filters in the kidney (called glomeruli) become damaged and leak protein into the urine. Patients with ESRD have 13 times the risk of death compared to other patients with type 1 diabetes. It is a common complication that affects nearly half of people with type 1 or type 2 diabetes after 25 years. Studies show that tight control of blood glucose levels delays the onset and slows progression of neuropathy. People who have the disease for more than 20 years and are insulin-dependent are at the highest risk. Numbness from nerve damage, which is common in diabetes, compounds the danger since the patient may not be aware of injuries.
Charcot foot or Charcot joint (medically referred to as neuropathic arthropathy) occurs in up to 2.5% of people with diabetes. When the acute phase has passed, patients usually need lifelong protection of the foot using a brace initially and custom footwear. Patients with no signs of retinal damage or low risk factors for retinopathy may only require screening every 2 - 3 years.
People with diabetes face a higher risk for influenza and its complications, including pneumonia, possibly because the disorder neutralizes the effects of protective proteins on the surface of the lungs. Women with diabetes face a significantly higher risk for urinary tract infections, which are likely to be more complicated and difficult to treat than in the general population.
Depression, in turn, may increase the risk for hyperglycemia and complications of diabetes. The changes in estrogen and other hormonal levels that occur during perimenopause can cause major fluctuations in blood glucose levels. Up to a third of young women with type 1 diabetes have eating disorders and under-use insulin to lose weight.
Two or three organs are usually needed in order to supply enough islet cells to have any effect on insulin production.
This generally requires multiple pancreas donors in order to achieve complete independence from insulin therapy.
However, many of these insulin-independent patients needed to resume insulin injections within 2 years.
Unfortunately, there are not enough pancreases available to make this procedure feasible for even 1% of patients. The operations help to prevent further kidney damage, and long-term studies indicate that they may even eventually reverse some existing damage. Kidney damage caused by diabetes most often involves thickening and hardening of the internal kidney structures. Continuous subcutaneous insulin infusion versus multiple daily injections of insulin for pregnant women with diabetes. The burden of diabetes mellitus among US youth: prevalence estimates from the SEARCH for Diabetes in Youth Study. Autologous nonmyeloablative hematopoietic stem cell transplantation in newly diagnosed type 1 diabetes mellitus. A licensed medical professional should be consulted for diagnosis and treatment of any and all medical conditions. King, Indiana University School of Medicine and Indiana University Center for Regenerative Biology and Medicine, Terre Haute, IN. According to many prominent researchers (including Achim Starke, MD and Jean-Frederic Brun), it does not. Giving a patient a diagnosis of reactive hypoglycemia (or prediabetes) involves looking at a few numbers, analyzing those numbers, and coming up with a diagnosis for the patient. Another 20% said she had a 1% chance, and an incredible 60% got it wrong and said she had an 81 or 90 percent chance of having cancer!
The red patient looks borderline, but the GTT cannot be used to accurately diagnose reactive hypoglycemia (to find out why, see my article on tests for reactive hypoglycemia).


It seems that fasting blood glucose as low as 95 are already sign of impaired glucose metabolism. There are many diabetics in my family and none of them have diabetes markers: they are all thin, with no large waist and with low blood pressure. However there’s other literature that suggests such a low score would indicate further testing to find out the cause. It took me a good 12-18 months for the cravings to fully subside, but eating a diet containing a balance of protein (I am not vegetarian), fat, and (after a couple of months) very complex carbohydrates worked for me. In non-insulin dependent diabetes (NIDD Type II DM), there is usually still insulin secreted, sometimes in excess amounts, but the cells do not respond to the signal as effectively, i.e. He tried cutting down the beer, but he was still going to the bathroom quite frequently, and the tiredness was getting more debilitating. Use these, together with the case histories, to come to a reasoned, evidence-based diagnosis. Immunoassays are capable of extreme specificity, sensitivity and precision and can allow many samples to be assayed rapidly.
Previously, the label was radioactive (RIA), but now more frequently, fluorimetric, colorimetric, chemiluminescent or enzymatic labels are used which have a lower risk in terms of health and safety. CANRISK has only been validated in a cross sectional convenience sample of patients and is longer than FINDRISC.
The American Diabetes Association recommends the FPG because it is easier, faster, and less expensive to perform.
Continued stress, from hyperinsulinaemia, gluco- and lipotoxicity, on the pancreatic-islet -cells results in failure to maintain sufficient insulin levels to compensate for the insulin resistance, leading to elevated glucose levels and the diagnosis of diabetes.
The release of insulin into the blood lowers the level of blood glucose (simple sugars from food) by enhancing glucose to enter the body cells, where it is metabolized. After delivery, blood sugar (glucose) levels generally return to normal, although 25% of these women develop type 2 diabetes within 15 years.
Children are more likely to inherit the disease from a father with type 1 diabetes than from a mother with the disorder. Epidemics of Coxsackie virus, as well as mumps and congenital rubella, have been associated with incidence of type 1 diabetes. At the point when insulin production bottoms out, however, type 1 diabetes usually appears suddenly and progresses quickly. Some doctors recommend it as a follow-up after FPG, if the latter test results are normal but the patient has symptoms or risk factors of diabetes. Blood tests for these autoantibodies can help differentiate between type 1 and type 2 diabetes. Testing should be performed yearly and perhaps every other year for patients with good lipid control and no evidence of heart disease. Microalbuminuria is also a marker for other complications involving blood vessel abnormalities, including heart attack and stroke. Patients who lose sensation in their feet should have a foot exam every 3 - 6 months to check for ulcers or infections. Patients should meet with a professional dietitian to plan an individualized diet within the general guidelines that takes into consideration their own health needs.
On the other hand, studies suggest that more than one-third of women with diabetes omit or underuse insulin in order to lose weight. People with diabetes and risk factors for myopathy should be monitored for muscle symptoms. Combining a statin with one of these drugs may be helpful for people with diabetes who have heart disease, low HDL, and near-normal LDL levels. However, some patients who take high-dose niacin can experience increased blood glucose levels. It can help relieve pain but has significant side effects, including nausea, constipation, and headache.
Unfortunately, tricyclics may cause heart rhythm problems, so patients at risk need to be monitored carefully.
If diabetes affects the nerves in the autonomic nervous system, then abnormalities of blood pressure control and bowel and bladder function may occur. Typical side effects are minimal but may include headache, flushing, and upper respiratory tract and flu-like symptoms.
However, patients with end-stage renal disease who are on dialysis generally need higher amounts of protein. Patients on dialysis usually need injections of erythropoiesis-stimulating drugs to increase red blood cell counts and control anemia. This includes checking your blood glucose before each meal, 1 - 2 hours after a meal, at bedtime, and possibly during the night. Tight blood glucose control is the best way to prevent major complications in type 1 diabetes, including those that affect the kidneys, eyes, nerve pathways, and blood vessels. Insulin glargine matches parts of natural insulin and maintains stable activity for more than 24 hours.
For example, one approach in patients who are intensively controlling their glucose levels uses 3 injections of insulin, which includes a mixture of regular insulin and NPH at dinner. The patient and doctor must determine the amount of insulin used -- it is not automatically calculated.
Pramlintide is used in addition to insulin for patients who take insulin regularly but still need better blood sugar control. Patients with type 1 diabetes have an increased risk of severe low blood sugar (hypoglycemia) that may occur within 3 hours following a pramlintide injection. The patient should also undergo yearly urine tests for microalbuminuria (small amounts of protein in the urine), a risk factor for future kidney disease. It may also occur in a person with type 1 diabetes who is not consistent with insulin therapy, or who has an acute illness or infection that makes their diabetes difficult to control. The most serious consequences of neuropathy occur in the legs and feet and pose a risk for ulcers and, in unusually severe cases, amputation.
Patients with diabetes should be aware of other warning signs of a heart attack, including sudden fatigue, sweating, shortness of breath, nausea, and vomiting. The consequences of both poor circulation and peripheral neuropathy make this a common and serious problem for all patients with diabetes. About 85% of amputations start with foot ulcers, which develop in about 12% of people with diabetes. Related conditions that put people at risk include peripheral neuropathy, peripheral artery disease, foot deformities, and a history of ulcers. Early changes appear similar to an infection, with the foot becoming swollen, red, and warm. People with diabetes are also at higher risk for developing cataracts and certain types of glaucoma.
The two primary abnormalities that occur are a weakening of the blood vessels in the retina and the obstruction in the capillaries -- probably from very tiny blood clots. Patients beginning a new or vigorous exercise program should have their eyes examined, as well as all patients planning pregnancy. Everyone with diabetes should have annual influenza vaccinations and a vaccination against pneumococcal pneumonia. In terms of sexual health, diabetes may cause decreased vaginal lubrication, which can lead to pain or discomfort during intercourse.
Long-term use (more than 2 years) of birth control pills may increase the risk of health complications.
Studies indicate that high blood sugar levels (hyperglycemia) can affect the developing fetus during the critical first 6 weeks of organ development. Women with diabetes also face an increased risk of premature menopause, which can lead to higher risk of heart disease.
Adolescents with diabetes are at higher risk than adults for ketoacidosis resulting from noncompliance. Researchers are continuing to work on refining the Edmonton protocol so that its benefits can be more sustainable and long lasting.
Researchers are looking for alternative approaches including the use of umbilical cord cells, embryonic or adult stem cells, bone marrow transplantation, and other types of cellular therapies. There is some evidence that heart disease and diabetic neuropathy improve after pancreas transplantation (although not retinopathy).
In order to arrive to your destination it will be very important to care for your last remaining engine.
Unfortunately, physicians frequently misread health statistics, and do not know the probability that someone has a particular disease given the results from a screening test. Additionally, the red patient has excess body fat around her hips, which actually protects from diabetes!
It seems that a reading above 145 at any moment in the glucose tolerance test is the best predictor of diabetes.
My understanding was that RH+weight gain put more of a strain on the pancreas, resulting in a higher chance of diabetes. Normally the system is well balanced ? excess energy intake is stored as glycogen or fat and blood glucose levels are kept within a narrow range. He retruned to the Student Health Centre and a more thorough examination showed that his weight was beolw normal, though he claimed to be eating normally.
Consequently they are especially useful for hormones whose concentrations are very low, or for distinguishing between compounds of very similar chemical structure.
The main limitation of immunoassays is that they do not distinguish biologically inactive molecules from biologically active molecules since both have the same antigenic determinants. Use the proforma on the following page and highlight the difference between type 1 and type 2 diabetes. Microvascular complications become apparent over time, depending on how well glucose levels can be controlled.
If blood glucose levels get too low, the pancreas secretes glucagon to stimulate the release of glucose from the liver. New advances in genetic research are identifying other genetic components of type 1 diabetes. Risk FactorsType 1 diabetes is much less common than type 2 diabetes consisting of only 5 - 10% of all cases of diabetes.
Eating disorders have become a serious problem within the general population and are especially dangerous in patients with diabetes. Because patients with diabetes may have silent heart disease, they should always check with their doctors before undertaking vigorous exercise. Although combinations of statins and fibrates or niacin increase the risk of myopathy, both combinations are considered safe if used with extra care. Moderate doses of niacin can control lipids without causing serious blood glucose problems.
Erythromycin, domperidone (Motilium), or metoclopramide (Reglan) may be used to relieve delayed stomach emptying caused by neuropathy.
However, these drugs -- darbepoetin alfa (Aranesp) and epoetin alfa (Epogen and Procrit) -- can increase the risk of blood clots, stroke, heart attack, and heart failure in patients with end-stage kidney disease when they are given at higher than recommended doses.
Intensive insulin treatment in early diabetes may even help preserve any residual insulin secretion for at least 2 years. Insulin glargine now offers the most consistent insulin activity level, but other intermediate and long-acting forms may be beneficial when administered twice a day. This rapid action reduces the risk for hypoglycemic events after eating (postprandial hypoglycemia). Lente (insulin zinc) is another intermediate insulin that peaks 4 - 12 hours and lasts up to 18 hours.
Another approach uses 4 injections, including a separate short-acting form at dinner and NPH at bedtime, which may pose a lower risk for nighttime hypoglycemia than the 3-injection regimen.
Newer, prefilled pens (Humulin Pen, Humalog) are disposable and allow the patient to dial in the correct amount.
They work by administering a small amount of insulin continuously (the basal rate) and a higher dose (a bolus dose) when food is eaten. This requires an initial learning period, including understanding insulin needs over the course of the day and in different situations and knowledge of carbohydrate counting. Home tests are available for measuring A1C but they tend not to be as accurate as the laboratory tests ordered by doctors. Shoes with a rocker sole reduce pressure under the heel and front of the foot and may be particularly helpful. Longer survival rates are probably due to improvements in monitoring and tighter control of blood glucose.
Other contributing factors are lack of health insurance and intentionally reducing insulin doses in order to lose weight, which occurs with adolescent girls in an effort to keep weight down.
It affects about 25% of patients who use insulin, nearly always people with type 1 diabetes. Urine tests showing microalbuminuria (small amounts of protein in the urine) are important markers for kidney damage. Symptoms of kidney failure may include swelling in the feet and ankles, itching, fatigue, and pale skin color. Peripheral neuropathy usually starts in the fingers and toes and moves up to the arms and legs (called a stocking-glove distribution). Lowering triglycerides, losing weight, reducing blood pressure, and quitting smoking may help prevent the onset of neuropathy. If these processes affect the central portion of the retina, swelling may occur, causing reduced or blurred vision. In this more severe condition, new abnormal blood vessels form and grow on the surface of the retina. Therefore, it is important that women with pre-existing diabetes (both type 1 and type 2) who are planning on becoming pregnant strive to maintain good glucose control for 3 - 6 months before pregnancy.
Young people who do not control glucose are also at high risk for permanent damage in small vessels, such as those in the eyes. These studies are still in very early stages, but researchers predict that there will be major advances in these fields in the coming years.
However, this procedure has significant surgical and postsurgical complications in patients with diabetes.
Links to other sites are provided for information only -- they do not constitute endorsements of those other sites. That’s according to a report by the journal Psychological Science in the Public Interest published in US News. To understand what happens in diabetes and why it is a serious problem, it is necessary to understand how the system is normally regulated. Nevertheless, like type 2 diabetes, the incidence of type 1 diabetes among children and adolescents has been rising over the past few decades.
A doctor uses the results from a creatinine blood test to calculate the glomerular filtration rate (GFR). Patients with diabetes should monitor their carbohydrate intake either through carbohydrate counting or meal planning exchange lists. Limit trans-fats (hydrogenated fat found in snack foods, fried foods, and commercially baked goods) to less than 1% of total calories.
Some evidence suggests that they contribute to about 20% of cases of recurrent ketoacidosis in young women. Short-acting insulin delivered continuously using a pump is proving to a very good way to provide basal rates of insulin.
Optimal timing for administering this insulin is about 15 minutes before a meal, but it can also be taken immediately after a meal (but within 30 minutes).
The older Minimed system measures glucose over a 72-hour period and has wireless communication between the monitor and an insulin pump.
About a quarter of the time, the results differ significantly from actual fingerstick tests, however. Usually the condition is manageable, but, occasionally, it can be severe or even life threatening, particularly if the patient fails to recognize the symptoms, especially while continuing to take insulin or other hypoglycemic drugs. In such cases, hypoglycemia appears suddenly, without warning, and can escalate to a severe level. The outlook of end-stage renal disease has greatly improved during the last four decades for patients with type 1 diabetes, and fewer people with type 1 diabetes are developing ESRD. The bones may crack, splinter, and erode, and the joints may shift, change shape, and become unstable.
One 10-year study reported that survival rate at 10 years was 76%, and two-thirds of the patients had both pancreas and kidney function. If you have a particular question about the information presented, you can send me an e-mail and I will try my best to help you. While type 2 diabetes has been increasing among African-American and Hispanic adolescents, the highest rates of type 1 diabetes are found among Caucasian youth.
The GFR is an indicator of kidney function; it estimates how well the kidneys are cleaning the blood.
Ketoacidosis is a significant complication of insulin depletion and can be life threatening. Ultralente insulin peaks at 10 hours and lasts up to 20 hours but varies greatly in activity from day to day.
Even a single recent episode of hypoglycemia may make it more difficult to detect the next episode. It typically develops in people who have neuropathy to the extent that they cannot feel sensation in the foot and are not aware of an existing injury. Major hemorrhage or retinal detachment can result, causing severe visual loss or blindness. Any duplication or distribution of the information contained herein is strictly prohibited.
On binding to its receptor, insulin induces activation of the insulin-receptor kinase (IRK) through autophosphorylation. With vigilant monitoring and by rigorously avoiding low blood glucose levels, patients can often regain the ability to sense the symptoms. Instead of resting an injured foot or seeking medical help, the patient often continues normal activity, causing further damage.
Doctors generally recommend transplants in cases of end-stage kidney failure or when diabetes poses more of a threat to the patient's life than the transplant itself. Recruitment of insulin-receptor substrate (IRS) proteins induces activation of phosphatidylinositol 3-kinase (PI3K) through binding the p85 subunit and activating the catalytic p110 subunit.
However, even very careful testing may fail to detect a problem, particularly one that occurs during sleep. PI3K activation induces downstream effectors, such as phosphatidylinositol-dependent kinase 1 (PDK1) and protein kinase B (PKB; also known as AKT), leading to translocation of glucose transporter 4 (GLUT4) and glucose uptake in muscle, and inactivation of glycogen-synthase kinase 3 (GSK3). IR activation can also activate the c-Cbl-associated protein (CAP) and mitogen-activated protein kinase (MAPK) pathways (not shown). Activation of STAT3 through JAK2 phosphorylation induces translocation of STAT3 to the nucleus.
STAT3 induces gene responses that reduce transcription of acetyl-coenzyme-A carboxylase (ACC), reducing malonyl CoA and fatty-acid synthesis, while increasing fatty-acid oxidation.
Endoplasmic-reticulum-bound or cytosolic PTP1B dephosphorylates membrane-bound or endocytosed insulin receptors and leptin receptors, causing their deactivation. Other PTP1B substrates, such as IRS1 and PTP1B, can downregulate IRK activity through a complex formed with growth-factor-receptor-bound protein 2 (GRB2). Hormones are chemicals that are released into the bloodstream and work on various parts of the body. A glucose tolerance test helps to distinguish between this normal pattern and the patterns seen in diabetes and impaired glucose tolerance.
